1.Whether the Sumerians were the first people to develop writing is uncertain.
为什么这句不用不定时的完成时态呢?E.g.Whether the Sumerians were the first people to have developed writing is uncertain.develop writing 不是过去发生的事情吗?为什么不用to have developed
2.Helen never submits anything to an editor until revising it several times.请问这句中
revising it several times"的主语是什么?是Helen还是editor?如何找主语啊?我怎么都分不清.
你们第二题没有一个回答正确的。主语是Editor

1.不定式在这里是做状语修饰people的,不用完成时态.不定式直接跟在谓语动词后面,而不定式的动作又发生在谓语动词之前才用完成时态,如I don’t know whether you happen to have heard but I’m going to study in the U.S.A.this September.不定式更多用来表示未来的动作,平时很少看到用完成式的.
2.这句是典型的not.until 结构,主语当然是Helen.找主语要看动作的完成者,在这里明显revise是Helen 做的而不是edit做的
